here's what i was trying to say:for the switch-up (or variation), at least one of the elements used, has to change drastically at some point.plus, the variation/switch-up part, has to be in a tempo and/or rhythm, different from your 'main beat'. does that make sense?

I had to break that sample into 7 sections and run all 7 through some SERIOUS processing to get rid of that NASTY background noise. Sounded like that sample was played through speakers and captured through a microphone....
